See how to check if your email address is hacked as over 700 million were affected

Over 700 million email addresses and a number of passwords have been leaked in what could be the biggest spambot dump ever seen.

Mr Hunt said that the 711 millions records leaked 'makes it the largest single set of data I've ever loaded into HIBP.'
